To all whom t may concern:

Be it known that we, VITA llama and LEON BENMAYOR, citizens of the United States of America, and residents or' Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Radiators, of which the following is a speciiication.

An object of our invention is a iadiator which aifords a thorough circulation of the air through its channels, and of the water through its channels.

Another object of our invention is a radiator which affords a maximum cooling surface and may be manufactured readily.

rIhese and other objects are attained by the means described inthe specification and illustrated in the accompanying drawing, in which e Fig. l, is a plan view of a portion of a radiator embodying our invention.

Fig. 2, is a sectionalview taken upon line 2-2 of Fig. l.

Fig. 3, is a sectional view taken upon line 3 3 of Fig. 2.

Fig. 4, is a detail view of one of the strips showing the depressions in the crowns of the convex portions of the strip.

Fig. 5 is a front elevation of a radiator of an automobile to which our invention may be applied.

The radiator embodying our invention comprises a series of sections A., B, of tubular members, having their ends sealed with solder D, E. Each of the sections A, B, is made from a strip of brass, which is of a width equal to the depth of the radiator. Each of the sections A, B, have in them a series of transverse corrugations which comprise convex portions a, o, and concave portions a, b. The concave portions a, o have formed in their crowns a series of cen tral depressions a2, b2. The strips are bent upon themselves at their centers a3, 63, and doubled so that the convex portions o, Z), come opposite each other so as to form tubular sections, and theconcave portions contact so that the depressions in the crowns thereof form channels at which connect the tubes which are formed by the convex portions. The sections A, B, are like in construction but their ends are reversed in the positions which they occupy in the radiator.

The sections A, B, are assembled by placing the convex portions of the strip adjacent to the concave portions a of the adljacent strips, so as to leave water channels G between the sections. The front and the rear ends of the water channels are closed by solder. is simply to dip the respective ends of the assembled strips in a bath of molten solder.

The operation of forming the sections is a simple one since the rounded corrugations with the depressions in the crowns of the concave portions may readily be formed by passing the strips through corrugated rollers.

The formation of the sections from the strips is a simple one requiring simply the doubling of the strips at `their centers and securing together adjacent ends of the strips. The assembling of the sections likewise is a simple operation.

In use the channels c between the air tubes H afford a ready circulation )of the air from one air tube to another so that all of the surfaces of the sections are cooled by the air, so that the maximum amount of cooling surface is afforded to the water passing down through the channels G.

lhat we claim is l. A radiator composed of a series of tubular sections, each section being composed of a strip of metal having in it a series of undulating transverse corrugations, each concave portion thereof having` in its crown a central depression, the strip being doubled or bent upon itself to cause the concave portion thereof to contact, and the convex portions thereof thereby forming tubes, the depressions in the convex portions forming channels between the adjacent tubes, the sections being assembled so that the tubes of a section are staggered with the tubes of adj acent sections thereby forming undulating water passages between the adjacent sections and the cooperative walls of the water passages being equidistant at any vertical cross section.
